Ni(OH)2 nanoflakes electrodeposited on Ni foam-supported vertically oriented graphene nanosheets for application in asymmetric supercapacitors.

Highlights: [•] Ni(OH)2/vertically oriented graphene nanosheets (V-GNs) was prepared. [•] Ni(OH)2/V-GNs had enhanced specific capacitance, cycling reversibility and stability. [•] Performance of Ni(OH)2/GNs/NF-AC asymmetric supercapacitor was studied. [ABSTRACT FROM AUTHOR]
